Build apps for Microsoft Teams

Microsoft Teams apps bring key information, common tools, and trusted processes to where people increasingly gather, learn, and work.

Apps are how you extend Teams to fit your needs. Create something brand new for Teams or integrate an existing app.

What are Teams apps?

Teams apps are a combination of capabilities. Some apps are simple (send notifications), while others are complex (manage patient records). When planning your app, remember that Teams is a collaboration hub. The best Teams apps help people express themselves and work better together.

Personal apps

Help people focus: A personal app is a dedicated space or bot to help users focus on their own tasks or view activities important to them.

Collaborate more conveniently: Display your web-based content in a tab where people can discuss and work on it together.

Turn words into actions: Conversations often result in the need to do something (generate an order, review my code, check ticket status, and so on). A bot can kick off these kinds of workflows right inside Teams.

Messaging extensions

Make it easier to multitask: With messaging extensions, you can quickly share external information in a conversation. You also can act on a message, such as creating a help ticket based on the content of a channel post.

Create apps for meetings: There are a few options for incorporating your app into the Teams calling experience.

Webhooks and connectors

Communicate with external apps: Incoming webhooks are a simple way to automatically send notifications from another app to a Teams channel. With outgoing webhooks, message your web service with an @mention.

Microsoft Graph for Teams

Utilize Teams data: The Microsoft Graph API for Teams provides access to information about teams, channels, users, and messages that can help you create or enhance features for your app (such as rich notifications).
